When Solaris 11 was released more configurations were moved into the service management framework, and moved out of configuration files, one of these changes was the hostname/nodename.
View Hostname in SMF
This will read back the configuration out of the SMF.
# svccfg -s system/identity:node listprop config<br /> config application<br /> config/nodename astring solaris11box<br /> config/loopback astring solaris11box
Change Hostname in SMF
We have two separate settings, which need to be updated.
# svccfg -s system/identity:node setprop config/nodename = astring: newname<br /> # svccfg -s system/identity:node setprop config/loopback = astring: newname
Review the Changes
# svccfg -s system/identity:node listprop config<br /> config application<br /> config/nodename astring newname<br /> config/loopback astring newname
Restart the Service to Reflect Changes
The system is now aware of the change, however it doesn’t use the change until the next reboot. We can accelerate this by restarting the system/identity:node service.
# svccfg -s system/identity:node refresh<br /> # svcadm restart system/identity:node
This will then show a system message reflecting the new hostname, to see the change in your shell prompt, you can spin off a child bash shell. You can also use the hostname command to view the current hostname.
